The deformation characteristics of Ti-5Al-5Mo-5V-1Fe-1Cr alloy during isothermal compression are investigated in this work. The alloy ingot is prepared by vacuum consumable furnace first. Then, thermomechanical processing and heat treatment are carried out. The microstructure shows the characteristics of Widmanstatten structure after heat treatment. The heat-treated material is subjected to isothermal compression test. According to the comparison of the coarsening degree of α grain under different experimental parameters. It is revealed that the strain rate has the largest influence on the stress field of the alloy during isothermal deformation.

The Ideal

In this paper,effect of the different forging processes on the microstructure and mechanical properties of the flat flat billets of TA15 titanium alloy was investigated.The flat billiets of 80 mm×150 mm×L sizes of TA15 titanium alloy are produced by four different forging processes.Then the different microstrure and properties of the flat billiets were obtained by heat treatment of 800 °C~850 °C×1 h~4h.The results show that, adopting the first forging temperature at T1 °C、slow cooling and the second forging temperature at T2°C 、quick cooling, the primary αphases content is just 10%, and there are lots of thin aciculate phases on the base. This microstructure has both high strength at room temperature and high temperature, while the properties between the cross and lengthwise directions are just the same. So the hot processing of the first forging temperature at T1 °C、slow cooling and the second forging temperature at T2°C 、quick cooling is choosed as the ideal processing for production of aircraft frame parts.
